Why one device is rarely enough
Acne scars are not a single problem on a single layer of skin. They form across the whole depth of the dermis — the surface texture, the pigment in the basal layer, the collagen scaffold underneath, and the fibrotic bands that physically tether a scar down from below. A single laser or a single needle can address one of those layers well, but it cannot reach all of them. That is the most common reason people feel their scars "stopped improving" after several sessions elsewhere: the treatment was effective, but it was working on the wrong layer for the scars they actually have.
The approach used at Clarity follows what dermatology literature describes as the gold standard for atrophic acne scars: combining complementary techniques in the same session rather than relying on one machine to do everything. Each tool is matched to the layer and the scar type it treats best, so a mixed face — which most real faces are — gets the right correction in every region at once. For the full background, see our cornerstone guide on acne scar types and how each is treated.
Why combine procedures in a single session
Treating every layer in one visit is not about doing more for its own sake — it is about giving the skin a single, coordinated healing response instead of several disconnected ones. When Subcision releases a band and MNRF rebuilds collagen in the same area on the same day, the new collagen forms into the space the release just created, rather than into a scar that is still being pulled down. Resurfacing the surface at the same time means the texture refines while that deeper remodelling is underway. Spreading those same steps across separate appointments tends to stretch the timeline, multiply the downtime, and leave each layer healing in isolation. Combining them is also why patients typically reach a meaningful change in fewer overall visits than a single-device approach repeated again and again.
The multi-layer protocol, procedure by procedure
Below is each procedure in the Clarity protocol, what it does mechanically, and which scar type it is aimed at. Dr. Big selects and weights these per case after the consult — not every face needs every step in every session.
Subcision — releasing the fibrotic bands
Many rolling scars are held down by bands of fibrous tissue that tether the skin to the layers beneath, creating the rolling, undulating shadow on the surface. Subcision uses a fine cannula or needle to cut those bands free, allowing the skin to lift back to a more even level and triggering new collagen as it heals. No laser passes over the surface can reach a band that sits below the dermis — this is mechanical work, and it is often the single most important step for deep rolling scars. Read more in subcision explained.
Best for: rolling scars, tethered atrophic scars.
Microneedle RF (MNRF) — rebuilding deep collagen
MNRF drives insulated micro-needles into the dermis and delivers radiofrequency energy at depth, creating controlled thermal zones that stimulate the skin to lay down fresh collagen exactly where it was lost. Because the energy is released below the surface rather than on it, MNRF remodels the deep scaffold of the skin while sparing the epidermis — which is why it pairs so well with Subcision in the same visit. It is the workhorse for restoring volume to atrophic scars over a series of sessions.
Best for: rolling and shallow boxcar scars, overall texture and pore size.
Ablative Fractional Laser — resurfacing the scar rim
Ablative fractional lasers (CO2 and Er:YAG) remove microscopic columns of surface tissue, prompting the skin to resurface with smoother, better-organised collagen. This sharpens the steep edges of boxcar scars and refines the surrounding texture so the scar rim blends into normal skin. Because it works on the surface, it produces the most visible short-term downtime of the protocol but also the clearest refinement of scar walls and texture.
Best for: boxcar scar walls, surface texture, enlarged pores.
Non-Ablative Fractional Laser — remodelling with less downtime
Non-ablative fractional laser heats columns within the dermis without removing the outer skin, stimulating collagen remodelling with a gentler recovery. It is useful for patients who need texture improvement but want minimal visible downtime, and for blending sessions between more intensive ablative treatments. It is often layered with the other tools to extend remodelling without adding much recovery time.
Best for: shallow scars, texture refinement, lower-downtime maintenance.
Picolaser — clearing post-acne pigment
Not every "scar" is a depression in the skin. A large share of what patients see is post-inflammatory hyperpigmentation (PIH) — the brown marks left after a breakout settles. Picolaser delivers ultra-short pulses that shatter excess pigment into fragments the body clears, evening out tone and brightening the post-acne marks that often make true scars look worse than they are. Clearing pigment frequently delivers the fastest visible "improvement" while the deeper collagen work matures underneath.
Best for: post-acne dark marks (PIH), uneven tone, dullness.
TCA CROSS — reaching ice-pick scars
Ice-pick scars are narrow, deep, and steep — too small for a laser handpiece to treat cleanly without damaging surrounding skin. TCA CROSS applies a high-strength trichloroacetic acid precisely into the individual scar pit, prompting controlled collagen formation that rebuilds the pit from the bottom up over repeated applications. It is a focal, pinpoint technique used alongside the broader resurfacing tools.
Best for: ice-pick scars and very narrow deep pits.
Know your scar type
Matching the right tool to the right scar starts with naming the scar. Atrophic acne scars — the kind that sit below the skin surface — fall into three classic shapes, usually mixed together on one face. There are also two flat marks that are commonly mistaken for scars but are treated very differently.
- Rolling scars — wide, shallow depressions with sloping edges that give the skin a rolling, uneven look. Driven by fibrotic tethering, so they respond best to Subcision plus MNRF.
- Boxcar scars — round or oval depressions with sharp, defined vertical walls, like a chicken-pox mark. Treated by resurfacing the rim with ablative fractional laser and rebuilding volume with MNRF.
- Ice-pick scars — small, narrow, deep pits that look like the skin was pierced. Too deep for general resurfacing — addressed focally with TCA CROSS.
- Post-inflammatory hyperpigmentation (PIH) — flat brown or dark marks left after acne, not a depression at all. Cleared with Picolaser and good photoprotection rather than collagen work.
- Post-inflammatory erythema (PIE) — flat red or pink marks from lingering inflammation, common on lighter skin. These often fade with time and vascular-targeted treatment rather than resurfacing.
Telling pigment apart from true scarring matters because the timelines and tools are different — flat marks can fade in weeks, while atrophic scars need a course of collagen-building sessions.
What to expect: results, sessions and downtime
The honest, realistic outcome for atrophic acne scars is improvement of about 60–80% over a course of treatment — not erasure. Scars that have existed for years are a permanent change in the skin's architecture; what good treatment does is make them substantially shallower, smoother, and far less visible under normal light. Anyone claiming acne scars can be made to vanish completely is overstating what is biologically possible.
How many sessions you need depends mostly on depth:
- Shallow rolling scars and post-acne marks often show a clear change within 3–4 sessions.
- Mixed and moderate scarring typically needs 4–6 sessions to reach a stable result.
- Deep boxcar and ice-pick scars usually need 5–6 sessions or more, with TCA CROSS repeated focally.
Sessions are spaced 4–8 weeks apart, because collagen is not built overnight — it remodels for weeks after each visit, and the real gain from a session only becomes visible once that cycle completes. Downtime is short: expect redness and light scabbing for about 3–5 days, with many patients back to normal routines the next day. For a deeper look at realistic expectations, see how much acne scars can actually improve. Results vary from person to person and depend heavily on consistent aftercare — at Clarity we describe this as the doctor contributing 30% of the result and the patient's ongoing skin care contributing the other 70%.
A typical recovery timeline
Knowing the recovery sequence in advance takes most of the anxiety out of it. On the day of treatment the skin looks red and may feel mildly swollen — an ice pack helps. Over days one to three there is light scabbing where the surface was resurfaced, so makeup is skipped and the cream the doctor provides is used instead. By days four to seven the scabs lift on their own and you can return to your normal skincare routine. From there the skin gradually clears and brightens while fresh collagen builds underneath, with the cumulative improvement — shallower scars and smoother texture — becoming clearly visible around the four-to-eight-week mark, which is exactly why sessions are spaced that far apart. The most important things you control during this window are strict sun protection and not picking at scabs, both of which directly affect how well a session pays off.

The doctor: Dr. Big performs every case personally
Every consultation, treatment plan, and procedure at Clarity is handled by Dr. Big — Thitikom Limrattanamekha, MD, an aesthetic doctor registered with the Thai Medical Council under license No. 61395. You see the same doctor at every visit; there is no rotation of staff and no handing off the actual treatment to an assistant.
Each plan starts with a Trica3D scan, a 3D skin-mapping assessment that records a baseline of your scar type, depth, and distribution. That baseline is what your follow-ups are measured against, so progress is judged on objective imaging rather than memory. Dr. Big will also tell you plainly if your case is not a good fit for these techniques — there is no pressure to treat. You can read more about Dr. Big and his approach.

Frequently asked questions
How much can acne scars realistically improve?
For most patients, acne scars improve by about 60–80% over a course of treatment — the exact figure depends on scar type, depth, and how consistently you follow aftercare. Existing scars do not disappear completely, and any clinic promising a 100% cure is overstating what the skin can do. At your consult Dr. Big assesses your scars under a Trica3D scan and tells you honestly what your case can expect.
How many sessions will I need?
It depends on scar depth. Shallow rolling scars and post-acne marks often respond within 3–4 sessions, while deep boxcar or ice-pick scars usually need 5–6 or more. Sessions are spaced 4–8 weeks apart so new collagen has time to mature before the next round.
Does it hurt, and how long is the downtime?
Numbing cream is applied before treatment, so the procedures are tolerable rather than painful. Afterwards the skin is typically red for about 3–5 days with light scabbing; many patients return to normal routines the next day and cover residual redness with mineral makeup once the surface has healed.
What does 5,000 THB per session actually include?
The 5,000 THB session price covers all of the main acne-scar procedures performed that day — Subcision, MNRF, Ablative and Non-Ablative Fractional Laser, Picolaser, and TCA CROSS where appropriate. You pay per session with no course packages and no points to count. Topical and oral medication, the aftercare cream, and injectable boosters are not included and are quoted after consultation.
